A hammock is great for camping. You sleep right under the stars without worrying about the terrain beneath you.
Eagles Nest Outfitters (ENO) makes the best lightweight hammock that I have found.
My cousin recently purchased an Eagles Nest Outfitters Hammock and, despite it being his first time hanging a hammock, it went up flawlessly. They are light enough to keep anywhere from your hiking bag to your pocket without any issues for those perfectly clear nights. I use my hammock every weekend, just park my car on the beach and hang it from my roof rack to a palm tree. They really allow you to relax wherever you are.
